Initial Physical Grades and Cognitive Stages After Acute Stroke: Who Receives Comprehensive Rehabilitation Services?

ObjectivesTo study the degree to which initial physical grades and cognitive stages of independence assessed by physical medicine and rehabilitation (PM&R) staff early after hospitalization for acute stroke relate to the decision to either provide rehabilitation in consultation or admission to a specialized rehabilitation unit (SRU) for comprehensive, high-intensity, multidisciplinary rehabilitation.DesignAn observational study.SettingEarly rehabilitation assessment by PM&R staff during patients' acute hospitalization for stroke in 112 Veterans Affairs facilities.PatientsThe sample included 8,783 veterans who were assessed by PM&R staff.MethodsShortly after hospital admission, functional status was determined according to 7 physical grades and 7 cognitive stages of increasing independence. Patients' physical grades and cognitive stages ranged at initial PM&R assessment from the lowest and most dependent “I” through intermediate “II, III, IV, V, or VI,” and ended with the highest at total independence “VII.” To assess the statistically independent effects of physical grade and cognitive stage, a multivariable generalized estimating equation was applied to account for within Veterans Affairs facilities correlation and to adjust for demographics, stroke type, comorbidities, clinical events before PM&R assessment, and facility-related factors.Main Outcome MeasurementsThe decision to admit patients to an SRU for comprehensive rehabilitation.ResultsOnly 11.2% of those patients assessed after stroke were admitted to an SRU after the acute management phase. After statistical adjustment, patients at the lowest physical grade (I) of independence had a 9-fold increased odds of admission to an SRU compared with those at the highest combined physical grades VI/VII (adjusted odds ratio 9.15, 95% confidence interval 4.31-19.39). In contrast, patients at intermediate cognitive stages of independence were the most likely to be admitted to an SRU. The presence of an SRU within the treating Veterans Affairs facility was strongly related to admission.ConclusionsPatients' physical grades and cognitive stages assessed early after stroke are strong determinants of referral for comprehensive rehabilitation.
